SSTL is developing the China DMC+4 microsatellite bus for the Beijing Landview Mapping Information Technology Ltd (BLMIT). The China DMC+4 enhanced microsatellite is an Earth observation spacecraft that combines SSTL’s standard Disaster Monitoring Constellation (DMC) multispectral camera with a high resolution panchromatic imager.
The customised microsatellite has specific enhancements to provide accommodation for the two imagers: a 32m multispectral imager currently flown on AlSAT-1, UK-DMC and NigeriaSat-1, plus a new 4m panchromatic imager developed under contract to SIRA Electro-Optics Ltd. The satellite bus provides highly agile attitude control to provide accurate pointing and the knowledge necessary for the mapping requirements of the mission.
